Related to several other threads I've recently started, I am attempting to uprez/upconvert an SD project to HD for a festival.
When I export my tiny 10 second test QT reference movie from FCP, I'm noticing interlacing artifacts that aren't there when viewing the material in the timeline.
Now to elaborate, the footage I"m talking about originated as 24p Advanced from an XL2, was then converted to 24 P standard and then to 60i/29.97 interlaced, and put in a 29.97 timeline to be mixed with other 60i footage that I wanted to keep looking interlaced (hence all the conversions of the 24p stuff). Finally got all this stuff looking right, exported to AVI, made DVDs, everything's cool. This was all done when I was using PC/VEgas. I then converted to a Mac/FCP, and brought this project in for uprezzing.
In a 29.97 timeline in FCP, the formerly 24p stuff looks fine. However, after exporting to a QT reference movie to play with in compressor (for the uprez), I keep seeing interlace artifacts on certain frames. IN the timeline, those aren't there at all. And these are WEIRD interlace artifacts, where it seems half the fields are missing. So on the "ghost" frame, instead of seeing every other line of the field, I'm seeing every two lines.
I don't know why it would look fine in the timeline, and after exporting "with current settings" cease to look fine when played back in the QT player. Any ideas?
